Recent trends in the study of switching processes in ferroelectrics

Abstract

Several ferroelectrics and materials showing ferroelectric-like switching behaviour have been widely investigated and both an exponential or power law of t_s on E have been reported. However, the mechanism of polarization reversal and domain dynamics show a complexity that makes it difficult to generalize and draw a common rule for all types of ferroelectrics. Radiation damage, internal biasing fields and defects alter the switching characteristics and in this review including some of the work of the authors on TGS, sodium nitrite DSP etc, the present trends in the study of switching and the electroluminescence during switching have been discussed.
